For the nails other than my forefinger I painted them pink, but with paint so I could scratch it off without damaging my nail. I then added brown for the wood and red for blood and touched it up until I was satisfied.

For the forefinger I painted some opaque plastic with the same colour pink as the other nails and ripped it in half, I then added dark red paint for the blood and more brown and red until I was happy :3 I took a picture of this while it was still wet for the effect but you could get the same effect with clear nail polishing it up :3 xx
